64892759 ÷ 638 
We're looking to find how many times 638 goes into 64892759.

Moving on to step 1:
The number 638 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 638

Let's proceed to step 2:
638 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 638

On to step 3:
638 can be fit into 648 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 638 from 648, we get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 638

Advancing to step 4:
638 can be fit into 109 0 times, resulting in a remainder of 109.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 109 and we're left with 109.
Grab the next digit (2) from the dividend, add it to 109, then carry on: 1092 / 638

Moving on to step 5:
The number 638 fits into 1092 1 times, leaving a remainder of 454.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
The remainder is 454 after subtracting 638 from 1092.
Include the next digit (7) from the dividend after 454, then repeat: 4547 / 638

Step 6:
638 can be fit into 4547 7 times, resulting in a remainder of 81.
Put 7 as the next digit of the answer. 
Result so far: 1017.0
The remainder is 81 after subtracting 4466 from 4547.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 638

Going ahead to step 7:
When dividing 815 by 638, we get 1 with a remainder of 177.
The next digit of our result is 1. 
Result so far: 10171.0
Deduct 638 from 815 and we're left with 177.
Grab the next digit (9) from the dividend, add it to 177, then carry on: 1779 / 638

Step 8:
638 can be fit into 1779 2 times, resulting in a remainder of 503.
Use 2 as the next digit of our solution. 
Result so far: 101712.0
Subtracting 1276 from 1779 leaves us with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

On to step 9:
638 can be fit into 5030 7 times, resulting in a remainder of 564.
Use 7 as the next digit of our solution. 
Result so far: 101712.7
Subtract 4466 from 5030 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Let's proceed to step 10:
638 goes into 5640 8 times with a remainder of 536.
Record the quotient 8 as the next digit in the result. 
Result so far: 101712.78
If we subtract 5104 from 5640, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Moving on to step 11:
5360 divided by 638 is 8 with a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 101712.788
Deduct 5104 from 5360 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Our division results in 101712.788 with a remaining 0.0256.
